Question 1 1 / 1 pts
a. Problem formulation b. Model validation c. Model verification d. Experimental design e. Output analysis f. Attendance at a Justin Bieber concert
(a),(b),(c),(d) and (e)
Correct answer
Question 2 1 / 1 pts
a. Problem formulation
(Lesson 4.1: Steps in a Simulation Study.) Which steps are regarded as essential for a successful simulation study? (There may be more than one correct answer.)
(Lesson 4.1: Steps in a Simulation Study.) Suppose that I have modelled the arriving calls to a call center as a Poisson process. What do I have to carry out in order to determine if that’s indeed a reasonable model assumption?
b. Model validation c. Model verification d. Attend a Justin Bieber concert
(b). Correct answer
Question 3 1 / 1 pts
a. Customers arrive at Justin's concert venue b. Justin forgets a lyric c. Justin sings the wrong note d. Angry customers depart the venue e. A customer is 11 years old
(a)–(d) are all events. [(e) is an attribute, not an event.]
Correct answer
Question 4 1 / 1 pts
True False
FALSE. Although activities are indeed times of specified length,waiting times typically need to be calculated from the sequence of customer arrival and service times | and so are not explicitly specified beforehand.
FALSE. Although activities are indeed times of specified length,waiting times typically need to be calculated from the sequence of customer arrival and service times | and so are not explicitly specified beforehand.
Correct answer
Question 5 1 / 1 pts
(Lesson 4.2: Some Useful Definitions.) Which of the following times could be regarded as events? (There may be more than one correct answer.)
(Lesson 4.2: Some Useful Definitions.) TRUE or FALSE? Customer waiting times are activities because these are typically explicitly specified in the simulation.
False Correct answer
Question 10 1 / 1 pts
True False Correct answer
Question 11 1 / 1 pts
True False Correct answer
Question 12 1 / 1 pts
True False Correct answer
Question 13 1 / 1 pts
True False Correct answer
Question 14 1 / 1 pts
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? The future events list contains all known upcoming events, including arrival times, departure times, and machine breakdown times.
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? The FEL can be updated any time an event occurs.
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? It is possible for the system state to change between consecutive event times.
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? In a simulation using the “next-event” time-advance mechanism, the simulation clock moves to the most-imminent event.
True False Correct answer
Question 15 1 / 1 pts
True False Correct answer
Question 16 1 / 1 pts
True False Correct answer
Question 17 1 / 1 pts
a. Event-Scheduling b. Process-Interaction
(b).
Correct answer
Question 18 1 / 1 pts
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? When a new event occurs, the simulation may update the chronological order of the FEL’s events by inserting new events, deleting events, moving them around, or even doing nothing.
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? Almost every discrete-event computer simulation language maintains a FEL somewhere.
(Lesson 4.3: Time-Advance Mechanisms.) TRUE or FALSE? In Arena, you are responsible for maintaining the language’s FEL.
(Lesson 4.4: Two Modeling Approaches.) Which is generally the easier simulation modeling approach — Event-Scheduling or Process-Interaction?
(Lesson 4.4: Two Modeling Approaches.) Which is the modeling approach adopted by Arena — Event-Scheduling or Process-Interaction?
Correct answer
Question 22 1 / 1 pts
a. Cost b. Ease of use c. Modeling “world view” (e.g., event-scheduling or process-interaction) d. Random variate generation capabilities e. Output analysis capabilities f. All of the above
(f).
Quiz Score: 22 out of 22
